View source for MITO8M-AN-001: Advanced multicore debugging, tracing, and energy profiling with Lauterbach TRACE32

=== TRACE32 configuration ===
In an SMP system the tasks are dynamically assigned by an SMP operating system to the cores. For debugging SMP systems, only one TRACE32 instance is opened and all cores are controlled from this instance.

TRACE32 PowerView distinguishes two types of information:
* Core-specific information which is displayed on a colored background. Typical core-specific information are: register contents, source listing of the code currently executed by the core, the stack frame.  TRACE32 PowerView uses predefined color settings for the cores.

* Information common for all cores, which is displayed on a white background. Typical common information are: memory contents, values of variables, breakpoint setting.
A selector is available to switch the core-specific information to a selected core.

On an SMP system the program execution on all cores is started with Go and stopped with Break. The same onchip breakpoints are programmed by the debugger at the same time to all cores. If a breakpoint is hit, TRACE32 selects the core on which the breakpoint occurred.
